This application claims the benefit of priority to U.S. ProvisionalPatent Application No. 62/423,182 filed Nov. 16, 2016, which isincorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

Animals, such as mammals and birds, are often susceptible to parasiteinfestations. These parasites may be ectoparasites, such as fleas andticks. Animals and humans also suffer from endoparasitic infectionsincluding, for example, helminthiasis which is most frequently caused bya group of parasitic worms described as nematodes or roundworms. Theseparasites cause severe economic losses in pigs, sheep, horses, andcattle as well as affecting companion animals (e.g. cats and dogs) andpoultry. Other parasites include those which occur in thegastrointestinal tract of animals and humans include Ancylostoma,Necator, Ascaris, Strongyloides, Trichinella, Capillaria, Toxocara,Toxascaris, Trichuris, Enterobius and parasites which are found in theblood or other tissues and organs such as filarial worms and the extraintestinal stages of Strongyloides, Toxocara and Trichinella.

One type of endoparasite which seriously harms mammals is Dirofilariaimmitis, also known as Heartworm. Other filarial endoparasites includeDirofilaria repens and Dirofilaria honkongensis, which can also infecthumans. The most common hosts are dogs and cats but other mammals suchas ferrets and raccoons may also be infected. Heartworms go throughseveral life stages before they become adults infecting the pulmonaryartery of the host mammal. The worms require the mosquito as anintermediate host to complete their life cycle. The period between theinitial infection when the dog is bitten by a mosquito and thematuration of the worms into adults living in the heart and pulmonaryarteries is six to seven months in dogs and is known as the “prepatentperiod”. L3 larvae migrate during blood feeding of the mosquito to thetip of the mosquito's mouth parts (labium), leave the mosquito and aredeposited on the skin of the dog where they then migrate through thebite wound into the host. Most L3 larvae molt to fourth-stage larvae(L4s) in canine subcutaneous tissues within 1-3 days after infection.Then, they migrate to the muscles of the chest and abdomen, and 45 to 60days after infection, molt to the fifth stage (L5, immature adult).Between 75 and 120 days after infection, these immature heartworms thenenter the bloodstream and are carried through the heart to reside in thepulmonary artery. Around seven months after infection, Dirofilariaimmitis adults reach maturity and sexually reproduce in the pulmonaryarteries and right ventricle. Adult males are around 15 cm in length,and females are around 25 cm in length and their normal life span asadults is calculated to be about 5 years.

Heartworm infection is a severe and life-threatening disease. Canineheartworm infection is preventable and prophylaxis treatment is apriority in heartworm endemic areas. Treatment of mature heartworminfection with an adulticide (e.g. melarsomine dihydrochloride) iscostly and can cause serious adverse side effects, thus prevention bymonthly administration of drugs that interrupt larvae development iswidely used. The goal of marketed heartworm preventive therapies in dogsis to prevent the development of the parasite to adult heartworms byinterrupting the Dirofilaria immitis life cycle post-infection.

The macrocyclic lactones (MLs, e.g. ivermectin, eprinomectin, milbemycinoxime, moxidectin, and selamectin) are the most commonly usedchemoprophylaxis agents and are administered at monthly or six-monthintervals. These drugs have been effective against Dirofilaria immitisinfective third-stage larvae (L3) deposited by the mosquito as well asmaturing fourth-stage larvae (L4). When administered monthly, MLs killL3 and L4 larvae acquired within the previous 30 days, and thus preventdisease caused by adult worms. MLs can also be used monthly in infecteddogs to suppress reproduction in adult worms and remove microfilariae,thereby reducing transmission and gradually causing the attrition ofadult worms (Vet. Parasitol. 2005 Oct. 24 133(2-3) 197-206).

In recent years, an increased number of lack of efficacy (LOE) caseshave been reported, in which dogs develop mature heartworm infectionsdespite receiving monthly prophylactic doses of macrocyclic lactonesdrugs. For example, Atkins et al., (Vet. Parasitol. 206 (2014) 106-113)recently reported that an increasing number of cases of dogs that testedheartworm antigen positive while receiving heartworm preventivemedication which suggests that some populations of Dirofilaria immitishave developed selectional resistance to heartworm preventives (AmericanHeartworm Society, 2010. Heartworm Preventive Resistance. Is itPossible, vol. 37. Bulletin of the American Heartworm Society, pp. 5.).Thus, there is an ongoing need to develop new anthelmintic agents withimproved activity against Dirofilaria immitis and other endoparasites.

Various parasiticides exist in the art for treating endoparasitesinfections in animals. In addition to the macrocyclic lactones, cyclicdepsipeptides with antiparasitic activity are known. PF1022A, a24-membered cyclooctadepsipeptide isolated from the fungus Myceliasterilia by Sasaki et al. (see J. Antibiotics 45: 692-697 (1992)), hasbeen found to exhibit broad anthelmintic activity against a variety ofendoparasites in vivo with low toxicity. The structure of PF1022A isshown below with the absolute stereochemical configuration of the chiralcarbon atoms indicated:

These compounds are described, for example, in U.S. Pat. Nos. 5,514,773;5,747,448; 5,646,244; 5,874,530; among others, which are incorporatedherein by reference. Emodepside is a semi synthetic analog of PF1022Acontaining a morpholine group at the para position of the aryl ring inthe phenyl lactate groups. Emodepside is a potent anthelmintic used incombination with praziquantel in the product Profender® for thetreatment of parasitic worms in cats and dogs. However, theanti-parasitic activity of PF1022A and emodepside is not satisfactoryfor the treatment of certain parasites, especially for the control ofDirofilaria immitis in mammals to prevent the establishment of heartwormdisease. Thus, there is a need in the art for more effectiveantiparasitic agents for treatment and protection of animals, e.g.mammals, fish and birds against parasites, in particular internalparasites including nematodes and filarial worms such as heartworm.

Surprisingly, it has been found that substitution of the alkyl groupsR¹, R², R³ and R⁴, which are 2-methylpropyl groups in the parent cyclicdepsipeptide PF1022 and also in emodepside, with certain groups improvethe in vitro metabolic stability of the compounds and may also improvethe activity of the compounds against endoparasites and ectoparasites.Furthermore, it has been surprisingly found that substitution of thecompounds of formula (I) with certain Cy¹ and/or Cy² groups alsosignificantly improves the in vitro metabolic stability of the compoundsof the invention compared with PF1022 and emodepside. In embodiments,the compounds of formula (I) with certain substituents will also exhibitimproved activity against ectoparasites.

It has also been surprisingly found that the spatial order ofsubstitution of R¹ to R⁴ also has a significant impact on the activityof the compounds. For example it has been found that when thenaturally-occurring 2-methylpropyl groups of PF1022A and emodepsiderepresented by positions identified as R¹ and R³ in the compound offormula (I) are modified the activity of the compounds is significantlyimproved over compounds where the 2-methylpropyl groups at the positionsR² and R⁴ are substituted. Thus, it is even more surprising that thecyclic depsipeptides having non-natural stereochemical configurations atone or more of the carbon atoms bearing the groups Cy¹, Cy², R^(a),R^(b), R¹, R², R³ and R⁴ retain the potent activity against parasites.The compounds of the invention where the groups Cy¹ and/or Cy² and atleast one of R¹, R², R³ and R⁴ are substituted with certain substituentsand wherein at least one of the carbon atoms bearing the groups Cy¹,Cy², R^(a), R^(b), R¹, R², R³ and R⁴ have a stereochemical configurationthat is inverted compared with the corresponding carbon atom in PF1022Ahave been found to have significantly improved metabolic stability andequal or improved efficacy against endoparasites including Dirofilariaimmitis microfilaria and/or L3 and L4 larvae and/or Haemonchus contortuslarvae.

The influence of certain substituents on one or more of R¹, R², R³ andR⁴ is also surprising. Thus, substitution of one or more of R¹, R², R³and R⁴ with fluoro has been found to significantly improve the in vitroactivity of the compounds of formula (I) on the motility of Haemonchuscontortus larvae and Dirofilaria immitis microfilaria compared withunsubstituted compounds (e.g. PF1022 or analogs where Cy¹ and/or Cy² aresubstituted phenyl but R¹ to R⁴ are 2-methylpropyl) or compounds inwhich the naturally-occurring 2-methylpropyl groups of PF1022A andemodepside, represented by positions identified as R¹ and R³ in thecompound of formula (I), are substituted with a methyl group. Inaddition, the substitution of R¹ and R³ groups with fluoro has beenfound to result in significantly improved in vitro activity against H.contortus larvae and D. immitis microfilaria compared with compoundssubstituted with fluoro at R² or other combinations. It is apparent thatthe type of substitution in groups R¹, R², R³ and R⁴ as well as which ofR¹, R², R³ and R⁴ are substituted have a significant influence on theactivity of the compounds.

Scherkenbeck et al. (Bioorg. Med. Chem. Lett. 8 (1998), 1035-1040)described that the replacement of the N-methyl leucine residues for aseries of related N-methylated amino acids such as isoleucine, valine,norvaline, alanine and phenylalanine resulted in nearly complete loss ofanthelmintic efficacy following oral administration in sheep.Furthermore, the publication reported that modification of half of theN-methyl leucine residues with either methyl or n-propyl side chainsalso surprisingly resulted in significantly reduced activity. It wasconcluded that the (L)-N-methyl leucine residues in the cyclicdepsipeptide PF1022A were a critical part of the pharmacophore andessential for in vivo activity.

Thus, it is surprising and unexpected that modification of the groups R¹to R⁴ in the compound of formula (I), which correspond to the N-methylleucine residues in PF1022A or emodepside, result in enhanced in vitrometabolic stability and/or improved activity compared with the compoundscontaining unmodified N-methyl leucine residues. It is also verysurprising and unexpected that the compounds of formula (I) in which thealkyl groups represented by R¹ and R³ are substituted with certaingroups exhibit significantly improved efficacy against endoparasitescompared to compounds that are substituted with the same groups at R²and R⁴ or in other combinations. In addition, the inclusion of certainsubstituents in groups R¹ to R⁴ and Cy¹ and Cy² result in improved invitro metabolic stability compared with unsubstituted compounds. Itfollows that an appropriate combination of the substitution at Cy¹ andCy² and R¹ to R⁴ in the compounds of formula (I) results insignificantly improved activity against endoparasites and improvedmetabolic stability in animals.

Furthermore, the substitution of the naturally-occurring 2-methylpropylgroups of PF1022A and emodepside, represented by positions R¹ and R³ inthe compound of formula (I), with certain substituents, including fluoroand methyl, has been found to improve the in vitro permeability of thecompounds. For example, compounds of formula (I) wherein Cy¹ and Cy² areeither both unsubstituted phenyl or p-fluorophenyl groups and R² and R⁴,respectively, are 2-methylpropyl fluoro-substituted were found to havesignificantly improved permeability compared with the compounds where R²and R⁴ are unsubstituted 2-methylpropyl. Further, compounds where Cy¹and Cy² are p-morpholino phenyl and R² and R⁴ are methyl-substituted2-methylpropyl were found to have significantly improved permeabilitycompared with emodepside (R² and R⁴=2-methylpropyl).

The characteristics described above for the compounds of formula (I) areexpected to result in compounds with superior antiparasitic efficacyagainst endoparasites and ectoparasites in or on animals.

It will be appreciated by those of skill in the art that the compoundsof the invention may exist and be isolated as optically active andracemic forms. Compounds having one or more chiral centers, includingthat at a sulfur atom, may be present as single enantiomers ordiastereomers or as mixtures of enantiomers and/or diastereomers. Forexample, it is well known in the art that sulfoxide compounds may beoptically active and may exist as single enantiomers or racemicmixtures. In addition, compounds of the invention may include one ormore chiral centers, which results in a theoretical number of opticallyactive isomers. Where compounds of the invention include n chiralcenters, the compounds may comprise up to 2^(n) optical isomers. Thepresent invention encompasses the specific enantiomers or diastereomersof each compound as well as mixtures of different enantiomers and/ordiastereomers of the compounds of the invention that possess the usefulproperties described herein. The optically active forms can be preparedby, for example, resolution of the racemic forms by selectivecrystallization techniques, by synthesis from optically activeprecursors, by chiral synthesis, by chromatographic separation using achiral stationary phase or by enzymatic resolution.

Veterinarily acceptable salts may be obtained using standard procedureswell known in the art, for example by reacting a sufficiently basiccompound such as an amine with a suitably acid functional group presentin the compound, or by reacting a suitable acid with a suitably basicfunctional group on the compound of the invention.

Processes for the Preparation of Compounds of Formula (I):

The compounds of formula (I) may be prepared by processes adapted fromthose described in U.S. Pat. Nos. 5,514,773; 5,747,448; 5,874,530;5,856,436; 6,033,879; 5,763,221; 6,329,338, 5,116,815; 6,468,966;6,369,028; 5,777,075; and 5,646,244, all which are hereby incorporatedby reference in their entirety. It will be appreciated by skilledpersons in the art that preparation of the compounds of the inventionhaving one or more inverted stereochemical centers compared with thenatural product PF1022A are made with the general process described inScheme 1 below except using intermediates having a stereochemicalconfiguration which results in compound having an invertedstereochemical configuration at the desired location in the moleculecompared. In addition, various synthetic methods for cyclicdepsipeptides have been reported in the chemical literature (seeLuttenberg et al., Tetrahedron 68 (2012), 2068-2073; Byung H. Lee,Tetrahedron Letters, 1997, 38 (5), 757-760; Scherkenbeck et al., Eur. J.Org. Chem., 2012, 1546-1553; Biosci. Biotech. Biochem., 1994, 58(6),1193-1194; and Scherkenbeck et al., Tetrahedron, 1995, 51(31),8459-8470) It will be understood by those skilled in the art thatcertain functional groups in the compounds and intermediates may beunprotected or protected by suitable protecting groups, as taught byGreene and Wuts, Protective Groups in Organic Synthesis, John Wiley andSons, Inc., 4^(th) edition 2006. Further, it will be apparent to thoseskilled in the art that the compounds and intermediates may be isolatedby standard aqueous work-up conditions and optionally purified. Forexample, the compounds or intermediates may be purified bychromatographic methods or crystallized to yield the desired product insuitable purity.

In one embodiment, the compounds of formula (I) where R¹, R², R³, R⁴,Cy¹ and Cy² are as defined above and R′, R″, R″′ and R″″ are methyl areprepared according to the general process described in Scheme 1 below.Modification of the stereochemical configuration of any of the carbonatoms bearing —CH₂Cy¹, —CH₂Cy², and/or the carbon atoms bearing R¹, R²,R³ and R⁴ provide the compounds of the invention.

Furthermore, the coupling of amines with carboxylic acids to form amidesis well known in the art and standard reagents may be used in thecoupling of a fragment with an unprotected amine with a second fragmenthaving a free carboxylic acid group (see for example, Peptide Synthesisby Miklos Bodanszky and Miguel Ondetti, Interscience Publishers, 1966;Amino Acid and Peptide Synthesis, 2^(nd) Ed. By John Jones, OxfordUniversity Press, 2002). The compounds may be prepared by solution phasesynthesis or using solid-phase synthesis with polymeric supports. Forexample, the formation of amide bonds may be mediated by activatingreagents such as carbodiimide reagents (e.g. dicyclohexyldiimide,diisopropyldiimide and(N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide.HCl) in combination withadditives such as N-hydroxybenzotriazole (HOBt) and the like. Inaddition, the formation of amide bonds in the synthesis may beaccomplished by using phosphonium reagents such as BOP(Benzotriazol-1-yloxy-tris (dimethylamino)-phosphoniumhexafluorophosphate), PyBOP(Benzotriazol-1-yloxy-tripyrrolidino-phosphonium hexafluorophosphate),PyBrOP (Bromo-tripyrrolidino-phosphonium hexa-fluorophosphate) and thelike. Other useful reagents for forming the amide bonds of the compoundsof the invention are the so called aminium/uronium-imonium reagents suchas TBTU/HBTU (2-(1H-Benzotriazol-1-yl)-N,N,N′,N′-tetramethylaminiumtetrafluoroborate/hexafluorophosphate), HATU(2-(7-Aza-1H-benzotriazol-1-yl)-N,N,N′,N′-tetramethylaminiumhexafluorophosphate) and the like.

The size of these microdroplets maybe less than 200 nm (1000 to 100,000 nm for emulsions). The interfacialfilm may be composed of an alternation of surface-active (SA) andco-surface-active (Co-SA) molecules which, by lowering the interfacialtension, allows the microemulsion to be formed spontaneously.

In one embodiment of the oily phase, the oily phase may be formed frommineral or vegetable oils, from unsaturated polyglycosylated glyceridesor from triglycerides, or alternatively from mixtures of such compounds.In one embodiment of the oily phase, the oily phase may be comprised oftriglycerides; in another embodiment of the oily phase, thetriglycerides are medium-chain triglycerides, for example C₈-C₁₀caprylic/capric triglyceride.

However, it is well withinthe skill level of the practitioner to use different compounds for eachcomponent of the same formulation. In one embodiment for the amount ofsurfactant/cosurfactant, the cosurfactant to surfactant ratio will befrom about 1/7 to about 1/2. In another embodiment for the amount ofcosurfactant, there will be from about 25 to about 75% v/v of surfactantand from about 10 to about 55% v/v of cosurfactant in the microemulsion.

This compound is prepared according to standard procedures fromcommercially-available 4-fluoroleucine (Chemical Abstracts RegistryNumber 857026-04-1). It will be appreciated that other groups R¹ to R⁴may also be prepared with different leucine analogs in a similar manner.For example, 3-fluoroleucine (Chemical Abstracts Registry No.171077-98-8, for example see Kaneko et al., Chem. Pharm Bull., 1995,43(5), 760-765) and 5-fluoroleucine (Chemical Abstracts Registry No.159415-71-1, see Moody et al., Tett. Lett., 1994, 35(30), 5485-8) arealso known and could be used to prepare compounds where R¹ to R⁴ aredifferently substituted fluoro leucine residues. In addition, it will beappreciated that alternative amino acids with different side chains mayalso used to prepare alternative compounds of the invention.

As shown in Scheme 1 above, the preparation of the compounds of theinvention is conducted by cyclization of the precursor 1-7 afterdeproctection of the terminal amine and carboxylic acid groups. It willbe appreciated by skilled persons in the art that using the generalprocess outlined in Scheme 1 a wide variety of compounds of theinvention may be prepared by selecting the appropriate monomer startingmaterials with the desired groups R¹, R², R³, R⁴, Cy¹ and Cy² in placeand preparing the dimers of general formulae 1-1, 1-2, 1-3 and 1-4 bydeprotection of the appropriate carboxylic acid and amino groups andamide formation.

Preparation Examples 1-28 shown below provide processes for thepreparation of various monomer compounds M1 to M50 substituted with awide variety of groups R¹, R², R³, R⁴, Cy¹ and Cy². In many cases, themonomers have the natural stereochemical configuration corresponding toPF1022A that enable the preparation of a diverse set of dimer compoundsused for the preparation of the compounds of the invention. Preparationof the corresponding monomer and dimer compounds in which the chiralcarbon atom has the inverted stereochemical configuration allows for thepreparation of compounds of the invention in which at least one carbonatom bearing the groups R¹, R², R³, R⁴, Cy¹ and Cy² has thestereochemical configuration described in Tables 1 to 5.
